Technical experts from the IBM Transaction Processing Facility (TPF) Development Lab share knowledge and information about the TPF product set - including z/TPF, TPF Operations Server (TOS), z/TPF Database Facility (z/TPFDF), and the TPF Toolkit.
IBM Knowledge Center content for z/TPF PUT 14 was refreshed September 29 to add all enhancements and maintenance APARS that were released since the most recent refresh in August. Enhancements since the August refresh include the following new function: FARF6 fixed file record support Watch this space for information about new content for PUT 14 in IBM Knowledge Center.
An enhancement to z/TPFDF data event processing now available on PUT 14 allows you to use data events with more z/TPFDF databases. Event message data event support for z/TPFDF, provided with APAR PI18980, allows you to collect updated LRECs or full subfiles when a subfile is modified. However, data event processing only collects data when a z/TPFDF subfile is opened with a hold. It is possible for applications to make updates to a subfile that is opened without a hold, as long as the file’s database definition (DBDEF)... [More]
FARF6 fixed file record support extends the use of FARF6 addressing to fixed file records for both z/TPF and z/TPFDF databases. FARF6 is an 8-byte symbolic file address. Previously, FARF6 addressing was supported for only 4 KB long-term duplicated pool records and 4 KB short-term pool records. With this enhancement, FARF6 addressing can be used for fixed file records of all sizes: small, large, and 4 KB fixed file records. In addition, you can use FARF6 fixed file record types when you create a fixed file system (FFS) or pool file system (PFS).... [More]
A new aparPrereq command has been added to the zTP F AP A R D o wnl o ad t oo l s package. This command identifies the cumulative set of prerequisite APARs for a given APAR and will report on whether those prerequisites have been applied to a specified set of TPF_ROOT folders. Refer to the help message within the aparPrereq command for details.
IBM Knowledge Center content for z/TPF PUT 14 was refreshed August 30 to add all enhancements and maintenance APARS that were released since the most recent refresh in June. Enhancements since the June refresh include the following new function: Crypto Express6S and OSA-Express6S support

As was done for JSON in PJ44767, DFDL support has been updated to allow an XML document to be created directly from binary data without the use of infonodes through the use of the tpf_dfdl_buildDoc API. This makes creating an XML document not only easier and faster, but enhancements have been made to the resultant layout of the XML document to make the document smaller than when built using DFDL and infonodes. The resultant XML document will also be in UTF-8 encoding, thus avoiding the need to translate it from EBCDIC. ... [More]
With Logging for z/TPF Support for MongoDB (PJ44239), we now support the ability to log queries, administration, and updates made with z/TPF support for MongoDB (PJ42292). This article will help you create and setup a Logstash plugin to receive logging events. What is Logstash? While a visit to their website will give you complete information ( https://www.elastic.co/products/logstash ), in general, Logstash provides an extensible data processing pipeline. How do I setup Logging for z/TPF Support for MongoDB? For more... [More]

Even though DFDL support has provided the ability to create JSON from binary data for several years, the process used an internal tree structure known as infonodes. The building of this internal tree before building of the JSON document provided some additional overhead that could be avoided. DFDL support has been updated to create a new API (tpf_dfdl_buildDoc) that does not use infonodes in the process of creating the JSON document. This new API makes it not only faster, but even simpler to use. This update also... [More]

The updates to z/TPF support for Java address various defects. They are designed to work with updates made to the IBM® 64-bit Runtime Environment for z/TPF, Java™ Technology Edition, Version 8. All of the z/TPF components, as well as the IBM Java runtime shared objects, can be loaded to a z/TPF system by using either the E-type loader (OLDR) or the image loader (TLDR). Apply both updates to the z/TPF system at the same time. Download and install the PJ44655_ibm-java-jre-8.0-4.5.tar.gz package from the... [More]

Greater than 64 KB TCP read support increases the maximum amount of data that can be received on a single TCP socket read-type function from 64 KB (65535 bytes) to 1 MB (1048576 bytes). With this enhancement, the cost of reading large TCP messages in customer applications is significantly reduced in terms of application complexity and CPU consumption in the z/TPF system. Non-SSL z/TPF WebSphere MQ sender/receiver channels, SRVCONN channels, and MQ Client are updated to use this support when reading large MQ messages. For more... [More]
User exits for MongoDB requests provides two user exits for you to control pre-request and post-request processing by using z/TPF support for MongoDB. You can use the pre-request user exit (UMON_pre_request) in the following ways: Check resources or status for each received MongoDB request. Reject requests and return the reason why the requests are rejected. Optionally disconnect the MongoDB session from the z/TPF server for MongoDB. With the post-request user exit (UMON_post_request), you can apply accounting logic based on the... [More]
IBM delivered z/TPFDF default key support for z/TPF support for MongoDB (APAR PJ44378) in April of 2017. This support provides a way for you to access z/TPFDF files that do not have default keys defined in the z/TPFDF database definition (DBDEF). Previously, the default keys could be defined only in the DBDEFs and doing so was optional. Many DBDEFs do not have default keys defined; instead, the z/TPFDF application uses a DBKEY macro or dfkey() function to specify the file organization when the application inserts or updates LRECs.
